Running W2000 Server Professional on Eithernet network of 9 computers via an older HP hub. Installed an new HP office printer on the network,ie. attached to the hub. Overnight the server quits communicating with printer. When I go to Control Panel\Administrative Tools\DHCP to look at the DHCP configutation I get error: "Not enough storage is available to complete this operation". I have to reboot server to re-establish communication..??. Tried everything I know but no success. Any suggestions appreciated
